Safety
The Alliance 9 has safety built into all design aspects, including:
- Anti Dive bow
- Superior stability
- Passengers feel inside a boat rather on a boat
- Less slamming due to use of narrow hulls
- Constant and smooth speed due to wave piercing outriggers and low drag coefficient
- Self draining main hull
Stability
Lateral Stability is achieved by the buoyancy the outriggers provide. This buoyancy is further
from the center line of the boat than any other small powerboat, including RIBs.
Longitudinal Stability is achieved by the Anti Dive bow that provides instant lift should you
hit a wave head on. The outriggers extend beyond the stern of the center hull preventing 'bow up'
situations. The Adam Younger designed multi step hull creates lift and stability throughout the speed envelope.

4. Smooth Ride
The deep V, multi-hull design has an inherently smoother ride for the passengers than mono-hull
powerboats as there is far less hull surface area for wave impacts to 'slam'. This results in a
much more refreshed and awake passengers when they reach their destination.
Performance
Depending on the engine and power train you select the boat is capable of speeds anywhere from
50 -> 100+ mph in offshore conditions. For a single engine boat you will not find any better.
The narrow hulls mean that this boat can maintain very high speeds in rough weather, safely
and comfortably. Other 'fast' boats are only able to achieve such speeds in dead calm conditions.

Transportability / Storage
With just a spanner you can reduce the boat into just 1.2 meter in width for ease of transport
or maximal storage on a mother ship.
Four boats can fit into a standard 40' container for shipping. Crane lifting points can be fitted.

Fuel Efficiency / Range
Due to the Adam Younger designed boat using narrow hulls and multiple steps the boat is incredibly
fuel efficient. For any given engine the boat is more fuel efficient at speed than any other similar
sized boat using the same engine. This allows you to be more relaxed about fuel costs.
Great fuel efficiency equals great range, in excess of 400 miles.
Repair and Maintenance
The boat has been designed to be disassembled using just a spanner. If you damage an outrigger,
replacing a new one is both quick and cheap. The engine bay has easy access from all sides.
As the center hull is just 1.2m in width it is easy for people to work on different parts of the
boat in a confined area.
Clean sheet design
For many decades now small boat designs have stagnated. Both designs and materials used have changed
very little, to us this is unacceptable. We have introduced a new approach to small boat design
For single engine craft the Alliance 9 is second to none in terms of:
- Performance
- Safety
- Fuel Efficiency
- Capabilities
Management Team
Alliance Boats are perhaps the only marine company that is headed up by a woman, different indeed!
An experienced designer Justyna, visited many boat shows and reviewed several decades of boat
magazines. The results were that small boat designs and materials have changed little in over 30 years.
Justyna decided to bring together an alliance of talented people headed by herself to create a genuinely
new boat design using the latest in marine technology and knowledge.
The head designer is Adam Younger. Adam is world renowned as one of the top marine designers
working today.
Our production facility is located in Lymington, England. All of the boat builders have several
decades of industry experience, headed up by Rod Ross-Smith
